This paper evaluates the impacts of increased coordination, accountability, and leadership among teams of responsible public o cials, with evidence from homicide investigations in Colombia. We randomly assigned the investigations of 66% of the 1,683 homicides occurring in Bogot a, Colombia, during 2016 to a new investigation procedure emphasizing these features. We nd a statistically signi cant 30% increase in the conviction rate in the treatment group relative to the control group. Indicators of the quality of the investigative process also improve,as well as the rate at which a formal accusation is presented before a court.Complementary ndings suggest that the treatment produces well-coordinated teams that can communicate more uently. Also, a survey of investigative team members reveal that work motivation, the extent to which they receive feedback on their performance, the pertinence and e ectiveness of their roles, and the perceived quality and coordination of the team all improve under the new scheme.
